ABSTRACT

Mexico ranks second in the world for Persian lime (Citrus latifolia) exports, making it the principal citrus exporter within the national citrus industry, exporting over 600,000 tons per year. However, diseases are the main factor reducing production, resulting in significant economic losses. Among these diseases, fungal diseases like dieback, caused by species of Lasiodiplodia, are an emerging issue in Persian lime. Symptoms include gummosis, twig and branch dieback, cankers, the necrosis of bark and wood, fruit mummification, and tree decline. The aim of this study was to investigate the occurrence and pathogenicity of the fungal species associated with twig and branch dieback, cankers, and decline of Persian lime trees in southern Mexico, and to elucidate the current status of the Lasiodiplodia species causing the disease in Mexico. During June, July, and August of 2023, a total of the 9229 Persian lime trees were inspected across 230 hectares of Persian lime orchards in southern Mexico, and symptoms of the disease were detected in 48.78% of the trees. Branches from 30 of these Persian lime trees were collected. Fungal isolates were obtained, resulting in a collection of 40 strains. The isolates were characterized molecularly and phylogenetically through the partial regions of four loci: the internal transcribed spacer region (ITS), the ß-tubulin gene (tub2), the translation elongation factor 1-alpha gene (tef1-α), and the DNA-directed RNA polymerase II second largest subunit (rpb2). Additionally, pathogenicity was assessed, successfully completing Koch's postulates on both detached Persian lime branches and certified 18-month-old Persian lime plants. Through multilocus molecular phylogenetic identification, pathogenicity, and virulence tests, five species were identified as causal agents: L. iraniensis, L. lignicola, L. mexicanensis, L. pseudotheobromae, and L. theobromae. This study demonstrates that in southern Mexico, at least five species of the genus Lasiodiplodia are responsible for dieback in Persian lime. Additionally, this is the first report of L. lignicola and L. mexicanensis as causal agents of the disease in citrus, indicating novel host interactions between species of Lasiodiplodia and C. latifolia.

ABSTRACT

SUMMARY OBJECTIVE: Bacterial vaginosis is the most common vaginal infection in reproductive-age women. If it is not treated, the quality of life will be reduced. In this study, the herbal medicine product Cymbopogon olivieri was used for its treatment. METHODS: This study was conducted with 90 women. The patients were randomly divided into two groups of 45: Cymbopogon olivieri and metronidazole. The treatment period was 7 days for each group. Improvement status was determined by eliminating at least three out of four of Amsel's criteria. A new variable with two order levels (negative and positive) was constructed. This new variable shows the status of the treatment process. Chi-square and Fisher's exact tests were used to examine the relationship between the new variable and treatment status. RESULTS: The results demonstrate that Cymbopogon olivieri and metronidazole significantly reduced the burning, itching, malodor, abnormal vaginal discharge, pH, clue cell, and positive whiff test (p<0.05). The findings also demonstrate that neither treatment was statistically different from the other for at least three of Amsel's criteria. CONCLUSION: This study shows that the effect of Cymbopogon olivieri on bacterial vaginosis is similar to that of metronidazole. Hence, Cymbopogon olivieri is a suitable option to treat bacterial vaginosis.

ABSTRACT

Cinnamon ( Cinnamomum verum J. Presl) is a well - known medicinal plant considered as an effective treatment for neurological disorders based on Persian medicine . The aim of the present study was assessing the effect of cinnamon oil, cinnamic acid, and cinnamaldehyde, on the in vitro model of Parkinson's disease (PD). Cinnamon oil, prepared in sesame oil, was phytochemically analyzed using high performance liquid chromatography (HPLC). Pheochromocytoma - 12 (PC - 12) cells were treated with 1 - methyl - 4 - phenyl - 1,2,3,6 - tetrahydropyridine (MPTP) as an in vitro model of neurodegeneration in PD. Cell viability, activity of caspase enzymes, and formation of reactive oxygen sp ecies (ROS) were evaluated. MPTP significantly decreased cell viability and increased Casp activity, as well as ROS formation. Cinnamon oil and cinnamic acid at 200 µg/m L could significantly reverse MPTP - induced abnormalities in PC - 12 cells including Casp activity and ROS formation. Our study supports the beneficial effect of cinnamon oil in neurodegeneration. Furt her investigations are needed to clarify the mechanisms and main active components.

ABSTRACT

Foi avaliado o tratamento homeopático de um felino com doença renal policística, moléstia hereditária muito comum na espécie felina. Por ser progressiva, o prognóstico depende do estágio de evolução da doença renal crônica, da resposta do felino ao tratamento inicial e do desejo do tutor em dar continuidade ao tratamento. A observação teve duração de 9 (nove) meses e a avaliação dos resultados foi realizada com o emprego de exame clínico e de exames complementares como imagens ultrassonográficas e exames laboratoriais. A terapia foi composta por medicamento homeopático constitucional Phosphorus 30CH e episódico Kresolum 6CH associado à introdução de dieta renal (ração seca adjuvante). O medicamento homeopático não provocou eventos adversos no animal. Os resultados sugerem que um animal com doença policística felina pode ser tratado pela homeopatia.(AU)


The homeopathic treatment of a feline with polycystic kidney disease was evaluated, a common hereditary disease in the feline species. Because it is progressive, the prognosis depends on the stage of evolution of the chronic kidney disease, the feline response to the initial treatment and the guardian's desire to continue the treatment. The observation lasted 9 (nine) months and the evaluation of the results was performed through clinical examination and complementary tests such as ultrasound images and laboratory tests. The therapy was composed of constitutional Phosphorus 30CH and episodic Kresolum 6CH homeopathic medication associated with the introduction of diet kidney diet (adjunct dry feed). The homeopathic medicine did not cause adverse events in the animal. The results suggest that an animal with feline polycystic disease can be treated by homeopathy.(AU)

ABSTRACT

The citrus agro-industry is one of the world's most important agricultural sectors. The Persian lime is one of six citrus fruit groups with economic significance. The technological lifecycle of Persian lime sector is assessed in this study using the growth S-curve approach. The objective is to depict the technology life cycle trajectory and current stage of the Persian lime citrus fruit, as well as each of its value chain phases, in order to facilitate better decision-making and technological strategies. The study uses technological patents collected from the World Intellectual Property Organization (WIPO) database from 1975 to 2009. The S-curve model of Persian lime and its value chain stages is generated using logistic mathematical regression. According to the findings of this study, Persian lime is in the maturity stage of the technology life cycle. As a result, the primary strategy could be cost reduction, process innovation, and price strategies to capitalize on market opportunities. When compared to other value chain phases, the transformation phase has the highest number of patents according to the value chain analysis and it is the unique value chain phase with statistical significance in the model. The transformation phase is also at the maturity stage of the technology life cycle. This creates opportunities in two ways: first, to adopt previously developed technologies in the transformation phase and improve process efficiency to reduce costs; and second, to reinforce innovative technological efforts in other phases of the Persian lime value chain, such as growth, harvest, or post-harvest.

ABSTRACT

OBJECTIVES: Autosomal dominant polycystic kidney disease (ADPKD), the most frequently diagnosed hereditary disease affecting Persian cats, is caused by a cytosine-to-adenine transversion (10063C>A) in PKD1, the gene that codes for polycystin-1. The objective of this study was to provide a preliminary estimate of the frequency of the pathogenic 10063C>A single nucleotide polymorphism (SNP) of PKD1 in Persian and Persian-related cat breeds in western Mexico. METHODS: Blood samples were collected from 104 cats (89 Persian, seven Persian crossbreed, five Siamese and three Himalayan cats). Genotyping was performed with our proposed PCR restriction fragment length polymorphism (RFLP) assay, as well as a previously established PCR-RFLP method for validation. The genotypes of control cats were corroborated by a commercial veterinary genetics laboratory. RESULTS: Our proposed PCR-RFLP assay and the validated PCR-RFLP methodology indicated that 24/104 (23.1%) cats in this study were heterozygous carriers of the 10063C>A SNP, including 23/89 Persian cats (25.8%) and 1/7 Persian crossbreed cats (14.3%). No Siamese or Himalayan cats were carriers. There were no discrepancies between the results obtained with our proposed assay and those obtained with the validation method or with commercial laboratory results. CONCLUSIONS AND RELEVANCE: The carrier frequency of the PKD1 10063C>A SNP in Persian and Persian-related cat breeds in western Mexico was found to be 23.1%. ADPKD frequencies among cat populations in Mexico have not been published previously. Genotyping assays can be used to facilitate the selection of breeding stocks by local breeders and veterinarians to avoid propagation of ADPKD.

ABSTRACT

OBJECTIVE: This study sought to describe the anatomical characteristics of the nasolacrimal duct of Persian cats as observed by computed tomographic dacryocystography. ANIMAL STUDIED: Ten cats weighing 3-6 kg (three live cats and seven cadaveric specimens). PROCEDURES: The animals were submitted to bilateral computed tomographic dacryocystography, totaling 20 nasolacrimal ducts. Dorsal, sagittal, and transverse planes were studied. Two additional skulls were also dissected following latex injection into the nasolacrimal duct. The length and width of the nasolacrimal duct and lacrimal canaliculi, and the distance between the nasolacrimal duct and the root of the upper canine tooth at the point of closest proximity were measured. RESULTS: The nasolacrimal duct followed a convoluted course, particularly in the middle and rostral portions. Duct stenosis (width reduction equal to or >75%) and dilations (width increase equal to or >50%) were also detected, particularly in the rostral portion. Nasolacrimal duct length and width ranged from 1.3 to 1.5 cm and 1.5 to 2.3 mm, respectively. Mean lacrimal canaliculus length and width corresponded to 3.1 mm and 0.4 mm, respectively. Mean distance from the nasolacrimal duct to the canine tooth was 2.4 mm. The root of this tooth interfered with the course of the nasolacrimal duct. CONCLUSION: This study provided anatomical information for clinical assessment of the nasolacrimal drainage system in Persian cats.

ABSTRACT

OBJECTIVE: Male infertility secondary to exposure to gonadotoxic agents during reproductive age is a concerning issue. The aim of this experimental study was to determine the effect of Loboob on sperm parameters. METHODS: 55 healthy rats were selected, weighted and divided into five groups consisting of 11 rats each. The control group received no medication. Rats in Treatment Group 1 received 10mg/kg Busulfan and rats in Treatment Groups 2, 3, and 4 received 35,70 and 140 mg/kg Loboob respectively in addition to 10mg/kg Busulfan. Finally, the sperm parameters and weights of the rats were compared using the Kolmogorov-Smirnov, non-parametric Kruskal-Wallis, and Dunn-Bonferroni tests. RESULTS: All sperm parameters and weights were significantly decreased among rats receiving Busulfan. All dosages of Loboob were effective to enhance the motility of slow spermatozoa, while only in the rats given 70 and 140 mg/kg of Loboob saw improvements in progressively motile sperm percentages (0.024 and 0.01, respectively). Loboob at a dosage of 140mg/kg improved sperm viability. It did not improve normal morphology sperm or decrease immotile sperm counts. Loboob did not affect mean rat weight. CONCLUSIONS: Loboob offered a dose-dependent protective effect on several sperm parameters in rats with busulfan-induced subfertility.

ABSTRACT

Foodborne viruses including hepatitis A virus (HAV), norovirus (NoV), rotavirus (RoV) and hepatitis E virus (HEV) are easily transmitted through contaminated seafoods. The current research was done to assess the incidence of RoV, NoV GI and GII,hAV and hEV in fish and shrimp samples caught from the Persian Gulf, Iran. Three-hundred and twenty fish and shrimp samples were collected. The presence of foodborne viruses were assessed by the real-time PCR. Forty-nine out of 320 (15.31%) fish and shrimp samples were positive for foodborne viruses. Distribution of hAV, NoV GI and NoV GII amongst all studied samples were 0.93%, 5.93% and 8.43%, respectively. hEV and RoV viruses were not found in studied samples. Parastromateus niger and Scomberomorus commerson fish and Penaeus monodon shrimp were the most frequently contaminated samples. Simultaneous incidence of hAV and NoV GI and hAV and NoV GII were 0.31% and 0.93%, respectively. Distribution of foodborne viruses in samples collected through spring, summer, autumn and winter seasons were 14.28%, 9.33%, 11.76% and 24.44%, respectively. Findings revealed that the incidence of foodborne viruses was significantly associated with seafood species and also season of sampling.(AU)

ABSTRACT

The status of the common intertidal snapping shrimp, Alpheus inopinatus Holthuis Gottlieb, 1958, is discussed based on newly collected material from Kuwait. Alpheus inopinatus was previously confused with morphologically very similar species in the Alpheus lobidens De Haan, 1849 species complex, formerly identified as A. crassimanus Heller, 1862 and herein tentatively referred to as A. cf. lobidens. The material herein examined strongly supports the validity of A. inopinatus based on several morphological characters, as well as differences in the colour pattern, compared to other members of the A. lobidens complex.

ABSTRACT

The alpheid genus Salmoneus Holthuis, 1955 is reported from Kuwait for the first time, with two species. One species, Salmoneus ikaros sp. nov., is described based on a single specimen from Failaka Island, extracted from the burrow of the callianassid ghost-shrimp Balsscallichirus masoomi (Tirmizi, 1970), together with the host. The new species is characterised by its peculiar eyes, which together with other characters separate it from all previously described species of Salmoneus. The second species, Salmoneus gracilipes Miya, 1972, is reported from Kuwait based on three specimens from two different localities and different habitats. Two specimens were found under coral rocks at a depth of about 7 m off Kubbar Island, whereas the third specimen was extracted from the burrow of the echiuran worm, Listriolobus cf. brevirostris Chen Yeh, 1958, at the type locality of S. ikaros sp. nov. at Failaka Island. Material identified as S. gracilipes from across its wide distribution range appears to be morphologically heterogeneous, possibly containing more than one species, and thus will need further studies.

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate the diagnostic concordance between the toothbrush and carpet techniques for the detection of Microsporum canis in cats in a field study. METHODS: Thirty-nine Persian cats from a cattery were used. Fungal culture samples from the haircoat of each cat were collected by stroking the coat with a sterile toothbrush and a 5 × 5 cm-sized sterile carpet square (n = 78 total samples). Specimens were inoculated onto Mycosel Agar and incubated at 25°C for 21 days. Both techniques were compared using the following parameters: number of plates without fungal growth, number of plates with contaminant growth and number of plates positive for dermatophytes. RESULTS: The feline population in the study cattery was 39. Thirty (77%) were symptomatic and nine (23%) asymptomatic. The diagnosis was made via carpet and toothbrush methods and 78 cultures were performed. On day 21, M canis was detected in all culture plates. No contaminant molds were observed. CONCLUSIONS AND RELEVANCE: The concordance rate between the carpet and toothbrush techniques among the 78 evaluable culture plates was 100%. Both methods are equally effective for collecting material for Mcanis culture. Additionally, both techniques are inexpensive and easy to perform in feline clinical practice.

ABSTRACT

Introduction: Pediculosis Capitis (head lice infestation) is the most common disease of the bloodsucking insect which affects approximately six to twenty million cases and results considerable economic burden annually. In this study we aim to investigate some medieval Persian views on the role of non-pharmacological treatment strategies for prevention and control of pediculosis and compare their prescriptions with current findings. Materials and methods: In this qualitative study, we reviewed some well-known Persian medicine (PM) textbooks based on the selected keywords (Shepesh, Reshk, Ghamal and Seyban) to collect the viewpoint of PM scholars for pediculosis and its treatments. Also, we searched in the databases such as PubMed, Science direct and Scopus about the topic. Results: Persian medicine scientists believed that there are six essential health principles (SetteZaroorieh), which can affect human health and prevent diseases including air, nutrition, exercise, sleep and wakefulness, exertion of unnecessary materials from the body and finally psychological concepts. Proper management of these essential factors can improve lifestyle of people affected with pediculosis and also play a key role in prevention of head lice infestation. Conclusion: There are several suitable recommendations for prevention and control of pediculosis according to essential health principles in PM which can consider beside current drug treatments and the individual health recommendations for complete control of the disease

ABSTRACT

Bioactive Phenols-loaded chitosan nanoparticles (PL-CNps) were developed by ionic gelation from Persian lemon (Citrus latifolia) waste (PLW) and chitosan nanoparticles. Response Surface Methodology (RSM) was used to determine the optimal Ultrasound-Assisted Extraction (UAE) conditions for the total phenolic compounds (TPC) recovery from PLW (58.13 mg GAE/g dw), evaluating the ethanol concentration, extraction time, amplitude, and solid/liquid ratio. Eight compounds expressed as mg/g dry weight (dw) were identified by ultra-performance liquid chromatography coupled photo diode array (UPLC-PDA) analysis: eriocitrin (20.71 ± 0.09), diosmin (18.59 ± 0.13), hesperidin (7.30 ± 0.04), sinapic acid (3.67 ± 0.04), catechin (2.92 ± 0.05), coumaric acid (2.86 ± 0.01), neohesperidin (1.63 ± 0.00), and naringenin (0.44 ± 0.00). The PL-CNps presented size of 232.7 nm, polydispersity index of 0.182, Z potential of -3.8 mV, and encapsulation efficiency of 81.16%. The results indicated that a synergic effect between phenolic compounds from PLW and chitosan nanoparticles was observed in antioxidant and antibacterial activity, according to Limpel's equation. Such results indicate that PLW in such bioprocesses shows excellent potential as substrates for the production of value-added compounds with a special application for the food industry.

ABSTRACT

BACKGROUND: Several studies have pointed out that certain snake venoms contain compounds presenting cytotoxic activities that selectively interfere with cancer cell metabolism. In this study, Pseudocerastes persicus venom and its fractions were investigated for their anticancer potential on lung cancer cells. METHODS: Lung cancer cells (A549) and normal fibroblast cells (Hu02) were treated with the P. persicus venom and its HPLC fractions and the cell cytotoxic effects were analyzed using MTT and lactate dehydrogenase release assays. Apoptosis was determined in venom-treated cell cultures using caspase-3 and caspase-9 assay kits. RESULTS: The treatment of cells with HPLC fraction 21 (25-35 kDa) of P. persicus venom resulted in high LDH release in normal fibroblast cells and high caspase-3 and caspase-9 activities in lung cancer cells. These results indicate that fraction 21 induces apoptosis in cancer cells, whereas necrosis is predominantly caused by cell death in the normal cells. Fraction 21 at the final concentration of 10 µg/mL killed approximately 60% of lung cancer cells, while in normal fibroblast cells very low cell cytotoxic effect was observed. CONCLUSION: HPLC fraction 21 at low concentrations displayed promising anticancer properties with apoptosis induction in the lung cancer cells. This fraction may, therefore, be considered a promising candidate for further studies.

ABSTRACT

AIMS: Breast cancer within the region continues to present challenges to the healthcare services. Strategies to shed light on clinical gaps could better support country-specific circumstances. The aims of the mapping study were to identify the gaps in the evidence base, for the management of breast cancer with relevance to Bahrain and the Gulf Region. In parallel, focusing on areas and directions of research, which are compatible with international and local clinical interests. It was envisaged that the mapping project would expose not only opportunities to improve support to the community but also illustrate the possible engagement of a government entity and a Nongovernment Organization in a private-public partnership. METHOD: An extensive literature review of local and international publications from the period between 1979 and 2015 was undertaken. Searches were conducted using free-text terms, singularly or combined, with no limiters, to provide unrestricted retrieval of available English studies. RESULTS: A total of 326 citations were identified, which after deduplication provided 277 unique citations of which included 236 studies within 13 different categories, relevant to breast cancer within the Gulf Cooperation Council (GCC). CONCLUSION: Contextualizing gaps in literature and, therefore, providing evidence-based decisions, not only support the enduser, but better support the country-specific challenges and burdens to healthcare. Three broad but key areas were identified after mapping of the literature, covering:screening and mammography, knowledge translation and dissemination, and lymphoedema postsurgical resection. Similar mapping projects could be undertaken by other national NGO's to better support the government and solidify the framework for a public-private partnership.

ABSTRACT

Several studies have pointed out that certain snake venoms contain compounds presenting cytotoxic activities that selectively interfere with cancer cell metabolism. In this study, Pseudocerastes persicus venom and its fractions were investigated for their anticancer potential on lung cancer cells. Methods: Lung cancer cells (A549) and normal fibroblast cells (Hu02) were treated with the P. persicus venom and its HPLC fractions and the cell cytotoxic effects were analyzed using MTT and lactate dehydrogenase release assays. Apoptosis was determined in venom-treated cell cultures using caspase-3 and caspase-9 assay kits. Results: The treatment of cells with HPLC fraction 21 (25-35 kDa) of P. persicus venom resulted in high LDH release in normal fibroblast cells and high caspase-3 and caspase-9 activities in lung cancer cells. These results indicate that fraction 21 induces apoptosis in cancer cells, whereas necrosis is predominantly caused by cell death in the normal cells. Fraction 21 at the final concentration of 10 μg/mL killed approximately 60% of lung cancer cells, while in normal fibroblast cells very low cell cytotoxic effect was observed. Conclusion: HPLC fraction 21 at low concentrations displayed promising anticancer properties with apoptosis induction in the lung cancer cells. This fraction may, therefore, be considered a promising candidate for further studies.(AU)

ABSTRACT

Abstract Melanogenesis is a biological process which led to the synthesis of melanin pigment. Abnormal melanin production results in melasma, solar lentigo, post inflammatory melanoderma, etc. In this study, we examined the potential inhibitory effects of 17 brown macroalgae from Persian Gulf on melanogenesis. The effects of various concentrations (100, 250 and 500 µg/mL) of methanolic extracts of macroalgae belonging to four genera (including: Padina, Colpomonia, Cystoseira and Sargassum) were studied on oxidation of L-Dopa by mushroom tyrosinase. Subsequently, the activity of macroalgae with high inhibitory effect on monophenolase activity of mushroom tyrosinase and zebrafish was investigated using L-tyrosine as a substrate. Anti-melanogenesis effects of algae extracts were studied on zebrafish as an alternative in vivo model. Kojic acid was used as a positive control. All the tested macroalgae showed inhibitory effect on activities of diphenolase and monophenolase (of mushroom tyrosinase). P. boergesinii exhibited the most in vivo anti-tyrosinase activity compared with other samples. P. boergesenii inhibited zebrafish tyrosinase more potent than kojic acid (83% vs 50% inhibition for kojic acid). Moreover, it reduced melanin synthesis in zebrafish 42% (kojic acid: 50%).

ABSTRACT

Dermatophytosis is the most common fungal infection in cats worldwide and plays an important role in both animal and human health due to their high zoonotic potential. Effective screening is a strong preventive measure and the fungal culture is quite useful but requires full laboratorial experience and it takes a long time to obtain the result. A rapid and accurate screening test for dermatophytosis in cats is crucial for the effective control of disease outbreaks. The aim of this study was to develop and evaluate the diagnostic efficacy of enzyme immunoassays (ELISA and Western blot [WB]) for the rapid and precise diagnosis of dermatophytosis in cats. Seventy cats of various ages were divided into three groups: S (symptomatic, n = 20), AS (asymptomatic, n = 30), and N (negative, n = 20). All animals were submitted to fungal culture and blood samples for carrying out the serological tests. A significant difference (P < 0.05) was found between IgG-specific levels of sera of Microsporum canis positive and negative animals. There was no statistic difference between groups symptomatic and asymptomatic. The ELISA test showed sensitivity of 94% and specificity of 75%. Receiver operating characteristic (ROC) analysis also showed higher diagnostic accuracy (AUC 0.925). The WB technique detected 13 bands, and the 50 kDa protein was considered the most immunogenic protein, observing reactivity in 83.3% in the symptomatic group and 66.6% in the asymptomatic group. The study concluded that ELISA and WB were useful tools to reliably detect cats that have been exposed to M. canis.
